UNITED STATES PATENT OFFICE.

LYMAN W. MERRIAM, OF FITCHBURG, MASSACHUSETTS.

lilPROVEMENT IN SHINGLING-BRACKETS.

Specification forming pari of Letters Patent No. 137,312, dated April 1,1873; application filed March 5, 1871. i

To all whom 'it may concern:

Be it known that I, LYMAN W. MEREIAM, of Fitchburg, in the county ofWorcester and State of Massachusetts, have invented certain Improvementsin Shin gling-Brackets, of which the following is a specication:

The nature of my invention consists in constructing a bracket to be usedupon the roofs of houses during the process of shinglin g, and whichbracket may be quickly applied without the use of nails or screws, andas readily detached when its service is no longer of use. It is alsonecessary that the fastening by which the said bracket is connected tothe roof shall be of such a nature that perfect safety to the user shallbe secured.

Description of the Accompany/ng Drawing.

Figure 1 is a perspective view of my bracket, in which A is the mainbody or web of the bracket, having dat projecting flanges B C on its topand vertical sides, the combined use of which, in combination with theexpanded foot D D, is to prevent the bracket from rocking and fallingover upon its sides. Fig. 2 is a detached view, showing the manner inwhich the ears engage with the shingle.

The expanded foot D D is constructed with a slightly-sharpenedknife-edge, so that it may be pressed more or less into the roof of thebuilding by means of the weight which is brought upon the bracket whilein use, and, in connection with a device upon the upper end of thebracket, (which will be hereafter described,) constitutes the means bywhich the bracket and scaiolding are held t0 the roof.

The web A has cast upon its upper end four ears or lugs, E E' and F F'.Two of these ears, E' F', being upon the back side of the web A, arerepresented in dotted lines inFig. 1, and two of the ears, viz., thosemarked F F', both of which are also represented in dotted lines, aresituated below the shingles G G.

The method of attaching the bracket to the roof consists in sliding theears or lugs F F' up under the shingles G G, when it will be found thatpressure upon the surface B will cause the ears E E' to press downward,and the ears F F' to press upward, producing upon the shingle G G aleverage cramp, which, in combination with the wedging form of theshingle, gives a very secure fastening. The lugs or ears E E' and F F',in combination with the shingles G G and the expanded foot D D,therefore constitute the mechanism by which the bracket is secured tothe roof. The lugs E E and F F', in combination with the shingles G G,constitute a strong and sufficient fastening without the use of theknife-edged expanded foot D D, which foot might be con structed invarious other forms.

What I claim as my invention, and desire to secure by Letters Patent,is-

A rooting-bracket having ears or lugs E E' and F F' and suitable feet DD, all substantially as described.
